32

Step-by-step explanation:

If he has 26 now, he had 16 before he bought the 10 more. If he had 16, he would have had 32 before he sold half of them

1

step-by-step explanation:

it's the only multiple of both and the least

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
